PILOT-BURNER EoE GAS-RANGES.

Patented Nov. 23, 1915.

Application filed April 2, 1915. Serial No. 18,673.

Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Pilot-Burners forGas-Ranges, of which the following is a specification.

My invention relates to the construction of detachable pilot burners forgas ranges and to the construction of the supports for the same embodiedin the frame of a range, coacting with a burner of my improvedconstruction.

My object is to provide simple and inexpensive pilot burners of acharacter adapted to be detachably mounted in a positive and rigidmanner in an opening or openings in the front of the range, the latterbeing adapted to coact with the burner to seat the same in the mannerdesired.

My invention consists in a pilot burner formed in the usual manner as acored T- shaped casting having openings along the upright and cross-barof the T, the casting having a pair of alined lugs on the two sidesthereof and a lug preferably extending downwardly slightly forward ofthe side lugs. The side lugs have horizontal bottom surfaces which restupon a horizontal shelf comprising a lower edge of an opening outthrough the front or side wall of the range, or an adjacent verticalwall of the range, the forward end of the burner being slipped over thenozzle extending horizontally from the manifold. The forward lugreferred to contacts the forward or outer surface of the vertical wallof the range to one side of the opening therein through which the burnerextends, whereby the burner is positioned longitudinally and isprevented from slipping off the manifold nozzle. Preferably I providethe range with a pair of parallel vertical front walls or membersthrough alined openings in which the pilot burner extends, the planelower surfaces of the side lugs of the burner resting on the horizontaledge of the opening in the inner of the two frame members, and thedownwardly extending lug contacting the outer side of the same member,while the burner may be additionally supported by having its lowersurface rest on the edge of the opening in the outer frame member.

In order that a clearer understanding of my invention maybe had,attention is hereby directed to the accompanying drawings forming partof this application and illustrating certain embodiments of myinvention. In the drawings, Figure 1 represents a side elevation of myimproved pilot burner, mounted in position in the range front, thelatter and also the manifold being shown in section, Fig. '2 is a planview of the same, the supporting members of the range being shown insection, Fig. 3 is a front elevation of the burner, together with aportion of the oven front, and Fig. 4 is a vertical section on line 4-4of Fig. l, the burner being shown in full.

Referring to the drawings, the burner 1 consists as stated of a simplecored T- shaped casting with openings 22 along the upright and cross-barof the T. The oven front through which the pilot burner extends whenmounted in position may comprise the oven front 3 and the heat deflector4, as shown in the drawings, this construction being described inapplication of Robert B. Caverly and myself, Serial No. 874,961, filedDecember 1, 1914, gas range.

As there described, the deflector plate 4 is formed of pressed metal inthe shape of a pan, the flanges of which are secured to the rearwardlyextending flanges 3' of the oven front. The manifold 5 is supported inany suitable manner in front of the range, and is provided with theusual cock 6 and the horizontal inwardly directed nozzle 7 The ovenfront 3 and deflector 4 are provided with alined openings 8 and 9therethrough, the opening 9 in deflector 4 having a horizontal loweredge 10. The pilot burner is provided with a downwardly projecting lug11 and a pair of side lugs 12, 12 having plane horizontal lower surfaces13. The burner is of curvedsection, as is usual, and lugs 12 provide ahorizontal support ing surface of sufficient width to give a stablesupport. When the burner is put in place, it is extended throughopenings 8 and 9 with its forward end slidably mounted upon the nozzle7. When so mounted, the bottom surfaces 13 of side lugs 12 are seatedupon the horizontal lower edge of opening 9, with lug 11 between ovenfront 3 and deflector 4, in position to contact the forward surface ofplate 4 below opening 9. The

burner also preferably rests on the lower edge of opening 8 as shown.Air is admitted into the burner through opening 14.

It is obvious that the burner described is mounted positively andrigidly, in such a manner that the same cannot get out of position orrock, while at the "same time the burner is mounted and removed by asimple manipulation. This is an improvement over eiitensions bolted tothem.

Having now particularly described my invention, what I claim and desireto protect by Letters Patent is as follows:

1. In a gas range the combination of a frame havingparallel verticalwalls spaced apart, said walls having alined openings, a gas pipepositioned inifront of the same having a nozzle directed horizontallytoward the opening in the front wall, and a pilot burner having aforward end adapted to slip over said nozzle, said burner extendingthrough the said openings and being seated on the lower edges thereof,and having a lug on its lower surface detachably seated between saidparallel vertical walls, said burner being of curved section, with aplane lower surface formed at a suitable point to rest on the lower edgeof one of said openings, substantially as set forth.

' 2. In a gas range,'theicombination of a frame having a vertical wallwith an opening therethrough, having a horizontal lower vedge, a gaspipe in front of the same, having a nozzle directed toward said opening,and a pilot burner comprising a cored casting of curved section, havinga front end adapted to slip over said nozzle, and having lugs onthesides thereof having horizontal bottom surfaces adapted to rest on thehorizontal surface comprising the lower edge of said opening, saidburner having means thereon adapted to coact with said frame to positionsaid burner longitudinally, substantially as set forth.

3. In a gas range, the combination of a frame having a vertical wallwith an opening therethrough, having a horizontal lower edge, a gas pipein front of the same, having a nozzle directed toward said opening, anda' pilot burner comprising a cored casting of curved section, having afront end adapted to slip over said nozzle, and having lugs on the sidesthereof having horizontal bottom surfaces adapted to rest on thehorizontal surface comprising the lower edge of said opening, and havinga downwardly extending lug forward of said side lugs, adapted to contactthe forward side of said wall below said opening, substantially as setforth.

4:- In a gas range, the combination of a frame having parallel verticalwalls spaced apart, having alined openings therethrough, one of whichhas a horizontal lower edge, and a pilot burner comprising a coredcasting of curved section, detachably seated in said openings, saidcasting having a lug adapted to contact the front of one of said walls,adjacent to the opening therein, and side lugs having horizontal bottomsurfaces adapted to rest on the said horizontal lower edge of one ofsaid openings, substantially as set forth.

5. In a gas range, a pilot burner comprising a cored casting of curvedsection, having side lugs thereon having horizontal lower surfacesadapted to form a support for the burner, and a lug forward of said sidelugs, adapted to contact a fixed vertical surface to position saidburner longitudinally, substantially as set forth.

This specification signed and witnessed this 26th day of March, 1915.
